To all whom it may concern:

Be it known that I, DANIEL Bonn, a citizen of the United States,residing at Milford, in the county of Kent and State of Delaware, haveinvented certain new and useful Improvements in an Apparatus for Dryingand Conserving Fruits; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the or heated air, or both together, are used forheating the dryingchambers, and the appara tus is adapted either todrying or conserving fruits, and whereby different chambers may beheated and treated diiferently at will.

I employ a set of drying-chambers, A A, of any suitable or desiredconstruction,iornr, and size, and they may be placed one on topofanother and side by side, as many as desired, the arrangement shown inthe drawings being a suitable one. These chambers are nearly or quiteair-tight, and their doors a a fit closely. The fruit-trays Z) I) inthem may be placed quite closely, one above another, to obtain as muchdrying surface as possiblc. These dryingchambers are mainly heated by asteam pipe or pipes, B, which extend and double or coil under eachchamber, so as to present as much heatingsurface as necessary to obtaintherequisite heatingpower therefrom. The pipe B, after extending to andcoiling or doubling under the several drying-chambers, may enter acondensed-steam chamber, 13, from which the water from the condensing ofthe steam is drawn through a pipe or spout.

Auxiliary to the heating steam pipe or pipes B, I employ a hot-air pipeor pipes, G, which communicate by branches 0 c with the interiors of theseveral drying-chambers, so as to admit the dry heated air from the pipeor pipes into the chambers. One furnace having a lieatingchamber, D,suffices to generate the steam for the steam pipe or pipes, andto heatthe air to pass through the hot-air pip e or pipes, the steam-coilitself heating the air before it passes through the said hot-air pipe orpipes. Also from the interior of each drying-chamber an exhaust-pipe, E,leads through short branch pipes d d, connecting with the severalchambers. Au exhaust-fan or air-pump, G, is connected with the other endof the exhaust pipe or pipes for drawing through the said pipe or pipesthe air and moisture or vapor from the dryingohainbers, so as tocontinually have dry air in the said chambers for drying the fruit. Eachconnecting branch 0 of the hot-air pipe or pipes O is provided with astop-cock and valve, f, to exclude the hot air, wholly or partially, asde sired, and each branch exhaust-pipe d is similarly provided with astop-cock, 9, so that any one or more of the chambers may be cut outfromaction when desired. Thus each chamber is made independent of theothers.

hen the fruit is to be dried in a chamber or chambers A, more or less ofthe heated air is admitted through the hot-ai r pipe to increase therapidity of the dryin When the chambers are used for conserving fruit,nohot air is admitted, since that would shrink the fruit, which is to beavoided.

I also provide for admitting steam from the steam pipe or pipes B intothe several cham bers A A through branch pipes 1', each having astopcock, k, to admit the steam or not. This may be especially useful inconserving fruit where a dry atmosphere is not desired.

\Vhat I claim as my invention is- 1.. In an apparatus for drying andconserving fruits, the combination of drying or COHSGIW ing chambers,steam heating pipe or pipes leading to the several chambers, hot-airpipe or pipes communicating with the interior of the several chambers,means for forcing heated air through the hot-air pipe or pipes into thesaid chambers, and valves for controlling the flow of hot air into theseveral chambers, for the purpose herein specified.

2. In an apparatus for drying and conserving fruits, the combinationofdryi ng or conservthe purpose herein specified.

ing chambers, steam heating pipe or pipes leadingto the severalchambers, steam pipe or pipes communicating with the interior of theseveral chambers, and valves for controlling the flow of steam throughthe latter pipes into the several chambers, for the purpose hereinspecified.

3. In an apparatus for drying and conservin g fruits, the combination ofdrying or conserving chambers, steam heating pipe or pipes leading tothe several chambers, steam pipe or pipes communicating with theinterior of the several chambers, hot-air pipe or pipes communicatingwith the interior of the several chambers, means for forcing heated airthrough the hot-air pipe or pipes into the said chambers, and valves forcontrolling the flow of hot air and steam into the several chambers, for

4. In an apparatus for drying and conservin g fruits, the'combinatiou ofdrying or conservin g chambers A A, steam heating pipe or pipes B,leading to the several chambers, branch pipes i i, communicating withthe interior of the several chambers, hot-air pipe or pipes O,communicating with the interior of the several chambers, exhaust pipe orpipes E, leading from the interior of the several chambers, eX- haustfan or pump G, and valves f gk for controlling the fiow of hot air andsteam into and through the several chambers, substantially as and forthe purpose herein specified.

In testimony whereof I affix my signature in presence of two Witnesses.I
